I have something to tell you! People talk constantly about ways to power cars. Whether it be stop-gap measures or their own ideas for "the ultimate fuel!" I've heard it all before: natural gas, electricity, biofuels, ethanol, biogas, hydrogen, algae-oil, methanol, butanol, you name it! People are getting ahead of themselves and making things a lot more complicated then it needs to be! Ironically, people have neglected the most practical, cheapest, absolute zero-pollution system there is. IT'S AIR!!! THE AIR YOU BREATHE!!! THE AIR THAT MOVES WITH THE WIND TO POWER WIND TURBINES; AIR IS FREE TO USE, AIR DOESN'T POLLUTE, AIR IS ABSOLUTELY INEXHAUSTIBLE, COMPRESSED AIR CAN BE HARNESSED TO POWER ANYTHING!!!
